TO ALL WHOM IT MAY CONOERN:

Be it known that I, J'. M. MASON, of .Neuf Albany, in the county of Floyd, 'and in the State of Indiana., have invented certain new anduseful Coupling of Shells to Metallic Rollers and Rollers to Mandrels; v and do hereby declare that the following is afulhelear, and exact clescriptonthereof, reference being had to the accompanying drawings, and to the vletters of reference marked thereon, making a'p'art of thsspeciic'ation.

In the annexed drawings, A represents an ordinary metallic roller, having a suitafble.'ope ninga, in the. v centre, for the insertion of the mandrel. B represents n. circular shell or band, which'is placedaiound the` exterior oi'` the roller A. The two areconnected by means of a dove-tailed tongue, e, vivhich'is. formed on the inner side ofthis shell, which fits into a. dove-tailed groove, 2:, ma e inthe roller A.` The tongue'- on the shelll and the groove in the roller are formed'the entire lengthof both. The roller Ar'nay be connected'to its-mam,

drel in like manner, and thev particular angle of the' tongue and groove being regulated to su it.` This shell B' may be of any preferred thickness, and used on'any metallic roller that has become irorn', reduced'in size, or

gotten out of round. v '-f v y- '-I In printing-establishments and-similar placesthe rollers beeouie worn-down' and cast away. Bythe method set forth the old roller maybe utilized by means of thc'lsh'ell, and the time spent-in'fextraoting the'rolle'r from itsmandrel, and placing a new roller thereon, isfsaved, as welll as the expense of vthe old roller, which is Asold as Yold metal.

In thecoloring or printing ofeo'tton goods, 'such as calico, the gurel is formed-on the face of a copper roller, andthe printing o f-any required number of 'yardsA made from thisfiigure. 'Ihe roller islt-hcn turned smooth, and a new figure cut-outhe second face, thusin time makingjthe roller ltoo small to he o`pera-tire; By means of the-shell connected as set forth fheold roller may be brought intense.

I do not coniinemyself toanyparticnlar kind of roller, or any purti'cu-lariuse forwhichfthefsaine i `s apiplied."l

Being aware that o ld rollers been utilized by the shrinking of bandsv thereon, I make rio claim"thereto.

Afterthe shell is conncctedto theroller, by-ine'ans of the tongue and groove, asl specified, they are securely held in place together., it'bcing quite impossible that the band or shell can slip or revolve-on the roller.

Having thus fully-deseribed iny'inv'ention,what I claim as now, and,desirevto secure byLetters Pa,tent,is-,

1; The shell coupled tothe rolleiA', bymeanso'f thejdo've-tailed tonguce, fitting into the'groove :c,all being constructed substantially in ,the nianner and used asv and for the purposes set forth.;

i 2. Utilizing the old roller by' means of, the shell, when connected together substantially as specified.

In testimony thatv I claim the foregoing, I have hereunto 'set my hand, this 18th day. of` November, 1867. J. MASON.'
